Tumbleweed Whenever you think of the Wild West of America, you think of cowboy movies and tumbleweed, perpetually tumbling around a desolate landscape.
Salt lowers the freezing/melting point of water, so in both cases the idea is to take advantage of the lower melting point. Ice forms when theÂ­ temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius). When you add salt, that temperature drops: A 10-percent salt solution freezes at 20 F (-6 C), and a 20-percent solution freezes at 2 F (-16 C). On a roadway, this means that if you sprinkle salt on the ice, you can melt it. The salt dissolves into the liquid water in the ice and lowers its freezing point.
The answer to all of the questions is no, there is no trick. The solution lies in the science behind the freezing temperature of water and how ice crystals form. This is also referred to as Supercooled Water. Everyone knows the freezing temperature of water is 32 degrees Fahrenheit or 0 degrees Celsius. When this temperature is reached, the water molecules freeze by forming ice crystals. Itâs easier for the water molecules to turn to ice on top of already formed crystals.
